View The National Register of Historic Places Nomination Form For This Historic Bridge

This bridge is one of a number of stone arch bridges in the county. It is noted for its arches which rest upon a taller pier than many of the arch bridges in the county.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 3-span, 74'-long stone arch bridge built in 1916 is listed in the National Register. There has been no change in the bridge's status since the previous survey.

Discussion of Surrounding Area

The bridge carries a 2 lane road over a stream in a rural setting of scattered 19th-century residences and a mill.

Bridge Considered Historic By Survey: Yes

Information and Findings From Pennsylvania's Stone Arch Bridge Management Plan

Discussion of Bridge

This bridge is recommended for long-term preservation. It ranks in the top third of all stone arch bridges under study in this plan. The bridge's character-defining historical features are largely intact, making its cost to rehabilitate relatively inexpensive. It lies in an area of low development potential, which will allow the bridge to carry its traffic into the future. It should be noted, however, that its transportation code is moderate, a function of the bridge's narrow roadway width and a center hump that restricts sight distance. The bridge has a high values code; it is listed in the National Register of Historic Places and it is part of a greenway. The bridge has received much public support (one letter, two telephone calls, and one meeting at which this bridge was a focus). Its waterway is adequate. However, the bridge's condition code is low due to exposed footers, which may result in scour. The bridge superstructure also has some cracks and loose stones. These conditions should be corrected using the procedures of the Maintenance Manual developed for this project.


The Caln, Edge Mill Road Bridge is owned by PennDOT and is ranked 22nd.
Condition Code = 44 - low
Transportation Code = 45 - moderate
Waterway Adequacy Code = 53 - moderate
Cost to Rehabilitate or Replace Code = 66 - very high
Anticipated Development Code = 58 - high
Recreational, Historical, and Cultural Values Code = 62 - very high
Public Input Code = 54 - moderate

Recommendation: Recommended for long-term preservation.
